T0 all whom t may concern:

Be it known that I, Gus'rav BnNiscH, a citizen of the United States of America, residing in N ew York, borough of Brooklyn, in the State of New York, have invented a certain new and useful Combined Mold and Face-Plate for Concrete, of which the following is a. specification.

ln the Construction of mausoleums, also numerous other structures, it is desirable to obtain the permanence and strength which is afforded by concrete used as a body material, while at the same time it is desirable to obtain a more finished surface than is possible when employing concrete alone. The object of the present invention is to provide a structure having such a concrete body, with all the advantages thereof, and at the same time having a more pleasing and highly-finished surface. For this purpose the body of the mausoleum or other structure is made of concrete, solid or reinforced, and there are provided plates of bronze or other suitable metalor material at the outer faces of the concrete, said plates and the concrete body being so connected in the process of casting the concrete that they form with the concrete when finished an integral mass showing on its faced sides the metal and on the other sides the rough surface of the uncovered concrete.

Similar reference numerals indicate corresponding parts in all the views.

The mausoleum comprises three principal parts, the base 10, side-walls or die 11, and top or roof 12. For constructing the base, four faee-iilates of metal are required. One of these, 13, is shown in Fig. 7. The plate shown faces one end of the linished base; a similar plate is provided at the opposite end, and two opposing longer plates of like construction form the sides of the base. Each of these plates, 13, 14, 15, 1G, is provided with a series of longitudinal ribs arranged at the inner side of the plate, horizontally, and spaced apart, and fastened to the plate by being soldered, brazed or otherwise secured thereto. Three of such ribs l?, are shown in Fig. T, but any number desired may be employed, depending on the height of the plate and the degree of security to the concrete which is to be obtained. The ribs are round or Of any other desired cross-section, as shown, or of other section such as to provide, back of the same, between the body of the plate and the rods, recesses 1S. When the base is to be of such size as to extend outwardly beyond the die, as in the mausoleum shown, each of the bronze plates 13, 14, 15, 16, is at its upper edge turned over angular-ly to the body of the plate, as shown at 19, thus forming in the finished structure a metallic protection to the water-table 2O of the base.

The plates are now each laid upon a level surface, with the ribs 17 uppermost, as shown Vin F 7, and strong concrete or cc- .ment is plastered or cast over 'the plate and the ribs thereof, to a height covering the ribs, as indicated in dotted lines in Fig. 7. The concrete is now allowed to set, and before the same has completely set dowels 22 of metal or any other suitable material are inserted partially into the concrete 23, so as to project upwardly therefrom.

The four plates 18, 14, 15, 16, having been prepared in the manner described, are now placed on any suitable casting-board or floor, with their long edges 21 resting thereon and their ends meeting, thus forming a mold closed on all sides and open at the top,v in the shape of the finished base, the plates being arranged with their ribs 17 at the inner side, toward the inside of the mold thus formed, and the angular or horizontal portions 19 of the plates likewise directed inwardly. The plates are secured in this position by any suitable bracing at their outer sides, or by tying or clamping the same together in any suitable well-known manner of securing in position the parts of a mold for casting. Concrete is now poured into the mold formed by the plates. The concrete surrounds the inwardly-projecting dowels and fills the space within the plates, and is floated off on the plane of the top of the horizontal portions 19 of the plates, as shown in Fig. 8. The concrete is then permitted to set, and when set the plates are found firmly secured to the inner mass 24 by the dowels.

The die 11 is formed separately from the base. For constructing the die, a metallic frame is provided for the front of the mausoleum. Said frame comprises side-members or Stiles 30, 31, having laterally-extending flanges 32, 33, and cross-bars 34, 35, 36, connecting the side-members. The crossbars are likewise of metal, and of channel shape, as shown in Figs. 5 and 8, and are secured to the stiles by soldering, brazing, bolting, or other means. The stiles are provided at their outer sides with tongues, 37, 38, respectively, and at their inner sides with grooves or mortises 39, 40.

A core of reinforcing material is next constructed, comprising supporting-rods 41 forming a frame, and wire-netting or other suitable reinforcing material 42 placed over and soldered or otherwise secured to the rods, at all sides thereof and at an inter-- mediate shelf, except that at one end of said cage-like core the reinforcing material v42 is omitted, and the cage is open at that end 43, as shown in Fig. 4. The core is now placed upon the front-frame with the rods 41 thereof at said open end 43 at the sides of the cage resting on the tongues, that is to say, the rod 45 resting on the tongue 37, and the rod 46 resting on the tongue 38, and the cross-rods 47 43, 49, respectively, entering the channel-bars 34, 35, 36, of the frontframe. Concrete, of a consistency self-supporting so as to enable it to be applied and retained by the core, is now plastered or cast over the core at all its sides, and the rear end, also in the channels 34, 35, 36. When set, the plastered core with the frontframe thereto attached by the cement in the channels and around the rods 47, 48, 49, is placed in normal position with its top 50, bottom 51, and intermediate shelf 52 horizontal, and the inside of the core is likewise y plastered, also the shelf 52 on both sides,

and the concrete allowed to set. The structure thus made forms the inner-shell of the die. For completing theV die, plates of metal are prepared, corresponding in size to the respective walls of the die at the outside of the same. One of the side-wall plates is shown in Fig/6. Each of the plates 53, 54, 55,'is provided with rods 17 as described with reference to the plates of the base, and

each is backed with a backing 23 of cement or concrete covering said rods, and having therein proj ecting dowels 22. The shell and its front-frame being placed on a suitable casting-floor,l the plates 53, 54, 55, are arranged around the same, with the front edges of the side-plates meeting the flanges 32, 33. The shell and the plates are of such proportions that when arranged in this manner a hollow wall-space of the desired width, depending on the thickness of the wall to be produced, is left between the shell and the plates. The plates being secured in position by any suitable bracing or clamping means, concrete is now deposited in the space between the shell and the facing. At the front of the walls the concrete enters in the space between the tongue 37 and fiange 32, and between the tongue 38 and flange 33, thus forming a projecting rib 56 between each tongue and the coresponding flange,

which secures the front-frame to the side-Y walls, of the die, as shown in Fig. 9.

For forming the doors, a face-plate 60 having secured thereto ribs 17, also a screwthreaded socket, 57, for each handle, is placed face down upon the casting-board, suitable mold-blocks of the height desired to produce the required thickness of the door are placed at the four sides of the plate, and concrete is cast upon the plate, being retained thereon by the surroundingA moldblocks, and the concrete is leveled off the height of the blocks, and allowed to set. Thereafter the front-plate 60 is drilled out opposite the sockets, and the handles 58 are screwed therein. The doors are of such thickness as to enter at their side-edges the grooves of the front-frame. For this purpose the groove 40 is made of greater depth than the groove 39, and the latter has its rear-face beveled, as shown at 59, Fig. 9. Then inserting the door, the edge 63 of the same is first inserted in the groove 40, which is of such depth that the opposite edge 64 is permitted to enter opposite the groove 39, and the door is then shifted laterally until the edge 64 enters the groove 39 and is guided by the beveled portion thereof and wedged thereby between said beveled face 59 and the front-face of the groove, thereby making a tight lit of the door with the frame. v

The top 12 is formed in a manner similar to that of the base already described, except that instead of casting the same directly on the casting-floor, a plate 70, providedwith ribs 17 a concrete backing 2,3, and dowels 22, is lirst placed yface down upon the floor, and the side-walls or plates 73, 74, 75, 76, are arranged around the same and suitably clamped in position. The mass of concrete is now poured into the mold thus formed. When set, the top is turned over so as to bring the top-plate 70 uppermost, and the 130 top is then placed in the proper position resting upon the die which has previously been placed upon the base.

By the construction described, there is produced a tWo-catacoinb mausoleum having all its exposed faces of inet-al, while at the saine time the strength of the concrete is secured for the mass of the structure. rEhe ribs running` longitudinally and horizontally ol the plates secure the saine to the concrete backing with such uniformity, and with such reinforcement oi' the plates themselves, that no buckling' of the plates occurs, or separation of the saine :troni the concrete inass.

lt is obvious that the invention is not limited to inausoleuins of two Catacombs, but niay be applied to Catacombs of any ninnber. By employing the basic forni oil? plate, as illustrated by either of the plates of the side-walls the die shown, and Varying the sizes of the plates, structures of an almost inlinite variety of forms may be inade. It is also obvious that the plates may be made in other than plane shape, and the Work thereby adapted to ornamental purposes.

l claim:

In a cataconib, the combination of a conlbined inold and face plate shaped to forni the uprights of a catacoinb proper, and a concrete eataconib proper having its exposed front edges inolded and set to the combined metal niold and face plate and permanently joined therewith by such setting, whereby a herinetical seal is torined between the concrete and Inetal inold or face plate, the coinplete front surface oi" the exposed front edges of the catacoinb proper being covered by the combined metal niold and face plate in full Yfaced surface contact therewith.

In testimony, that I claiin the foregoing as iny invention, l have signed iny naine in presence of two subscribing witnesses.
